AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.

AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

Forecast Discussion: Air quality has generally been good to start the week. The only exception to that was on Tuesday, when some northern areas of the forecast region reached moderate. Monitors are good so far this morning. Expect a continuation of the good air quality through the weekend, as the flow is from the west and northwest until Saturday evening. At that time, winds will shift to the south and southwest as a surface low moves north of the area. All areas are forecasted to see snow on Sunday morning. Southern areas switch to rain during the day, while central areas could see a mix of precipitation. Some small accumulations are possible in Central Indiana. A weaker secondary low could move through on Monday morning, continuing the precipitation threat.
